  • radar can be classified in various ways.
  • monostatic radar a signal transmitter and a receiver are integrated and share an antenna.
  • the advantage is that a target echo signal and a local oscillator of the receiver are naturally coherent and thus signal processing is convenient.
  • the disadvantage is that signal transmission and reception cannot be performed at the same time, and signal waveforms with a certain duty cycle must be adopted. Consequently, a detection blind spot is caused and a complex algorithm needs to be used for compensation.
  • signal transmission and reception are performed at the same time, and transmission and reception are strictly isolated, but this is difficult for high-power military radar.
  • a signal transmitter and a receiver are located at different locations.
  • the advantage is that a signal may be transmitted and received at the same time, and continuous-wave waveforms may be used for detection.
  • the disadvantage is that it is difficult to achieve co-frequency and coherence between the receiver and the transmitter, leading to complex signal processing.
  • radar technology can be used in either monostatic mode or bistatic radar mode.
  • a transmitted signal and a received signal share an antenna, and the transmitted signal and the received signal enter different radio frequency processing chains through a circulator.
  • continuous wave signal waveforms can be used for blind-spot-free detection, provided that the received signal and the transmitted signal are well isolated, typically requiring an isolation of about 100 dB to eliminate masking of the received signal caused by leakage of the transmitted signal. Since the receiver of monostatic radar has complete information on the transmitted signal, signal processing can be performed through matched filtering (pulse compression) to achieve high signal processing gain.
  • bistatic radar mode there is no isolation between transmitted and received signals, greatly simplifying hardware complexity. Since radar signal processing is based on known information, in NR integrated sensing and communication applications of 5th generation mobile communication technology (5th Generation Mobile Communication Technology, 5G), known information such as synchronization signals and reference signals can be used for radar signal processing. However, due to the periodicity of synchronization signals and reference signals, an ambiguity diagram of signal waveforms is no longer thumbtack-shaped but thumbtack-board-shaped, increasing the ambiguity in delay and Doppler, and the main lobe gain is significantly reduced as compared with the monostatic radar mode, reducing the measurement range of distance and speed. With proper parameter set design, the distance and speed measurement requirements for common targets like vehicles and pedestrians can be met. Additionally, the measurement accuracy of bistatic radar is related to the relative positions of the transmitter and receiver concerning the target, and appropriate transmitter and receiver locations need to be chosen to improve detection performance.
